إريك شيري: محاضِر في الكيمياء وتاريخ وفلسفة العلوم في جامعة كاليفورنيا، بلوس أنجلوس. ألَّفَ ثلاثة كتب، من بينها «الجدول الدوري: قصته وأهميته».
"في سنة 1913 ، توصّل الفيزيائي الإنكليزي هنري موزلي إلى أسلوب أنيق لترتيب عناصر الجدول الدوري بناءً على العدد الذرّي بدلاً من الوزن الذرّي. وسرعان ما اتضح أن هناك سبعة عناصر ناقصة بين الهيدروجين (العنصر رقم 1 ) واليورانيوم (العنصر رقم 92). في هذا الكتاب، يقدّم إريك شيري القصص الشيّقة لهذه العناصر السبعة: البروتكتينيوم، والهفنيوم، والرينيوم، والتكنيتيوم، والفرنسيوم، والأستاتين، والبروميثيوم. ويتّبع الكتاب الترتيب التاريخي للاكتشاف في فترة ما بين الحربين العالميتين الأولى والثانية تقريباً، بدءاً بعزل البروتكتينيوم في سنة 1917 وانتهاءً بعزل البروميثيوم في سنة 1945 . ويتتبّع الأبحاث التي سبقت اكتشاف كل عنصر، والتجارب المحورية، والكيميائيّين المعنيّين، والطبيعة الكيميائية للعنصر الجديد، وتطبيقاته في العلم والتكنولوجيا ."
